Hello! I have many lights illuminated on the dash such as ABS, ESP BAS, traction, hand brake.

I would like to start diagnosing the problem by checking inputs and outputs on the ABS module but i don’t have a wiring diagram. I could only find ECM diagram.

Let me know how you would tackle such a problem.

Thank you

Hi,

Chances are the problem is related to a faulty wheel speed sensor and not the module. Even low brake fluid can set all these codes.

Before we dive into a control module, check for a signal at each wheel speed sensor. Here is a link that explains how it's done. All you will need is a voltmeter or multimeter.

I have attached the wiring schematic below for the ABS circuits. I hope they help.

Let me know what you find.

Take care,

Joe
